PLB HDPE Ducts

BSNL GR- GR/CDS-08/02 Nov. 2004

CONSTRUCTION: Tijaria Permanently Lubricated HDPE Ducts are formed by co extrusion technique and are used for laying Optical Fiber Cables as under ground ducting/conduits.

MATERIAL: The base raw material being used for the manufacturing Permanently Lubricated Ducts is High Density Poly Ethylene. The grade of raw material is ultra violet grade and is confirming to IS:7328-1992 & IS:2523 or ISO:1183 & ISO:1133 and is designated as PEELA- 50T-012 (CACT Approved) and inner layer permanently lubricated material DOW CORNING grade-50MB002.

APPLICATIONS: Telecommunication,  Computer Network, Automatic Signaling, Railways Information Network, Highways, Cable Service providers, Broad Band networks, Electric cable installation etc.

ADVANTAGES:

  • Reduction of stress on cable during installation.
  • Installation of Longer lengths made feasible.
  • Negotiations of cable movement through bends and deflections are easier.
  • Reduction of number of joints and minimizes number of splices.
  • Faster and easy installation of cable with lesser man power.
  • Reduction of overall cost of installation, maintenance and future upgrades.
  • Retains it's properties throughout it's life.
  • This does not have toxic and dermatic hazards and is safe handing.

All above mentioned test on PLB HDPE DUCTS are conducted in-house as per DOT specification No. G/CDS-08/02 Nov.2004 and ISO:3126.

ASSOCIATED ACCESSORIES & TOOLS:

1. Plastic Coupler            : To join two duct lengths-air tight and water tight.
2. End Plug                    : To seal duct ends prior to the installation of the cable.
3. Cable Sealing Plug       : To seal duct ends after insertion of the cable.
4. End Cap                     : Made of hard rubber, fitted on both ends of duct coil after manufacturing.
5. Duct Cuter                 : To cut duct cleanly and with square ends.
6. C Spanner                  : To tighten plastic coupler.
